BRINP1, or BMP/retinoic acid-inducible neural-specific protein 1, is a member of the BRINP family of proteins. It is primarily expressed in the brain and plays important roles in neuronal processes such as neurodevelopment, synaptic plasticity, and neuronal survival. BRINP1 is induced by factors like bone morphogenetic proteins (BMPs) and retinoic acid during early neural development, indicating its involvement in the patterning and differentiation of neural progenitor cells. Its expression is tightly regulated both spatially and temporally in the developing brain, highlighting its key role in neural maturation and function.
